Windows only: Microsoft Office Accounting Express 2007 is a new accounting suite designed with startups, small businesses, and eBay sellers in mind. Oh, and it's free.

Free? Microsoft software? Free? Sure enough, this surprisingly versatile package costs absolutely nothing. Certainly Microsoft's goal is to lure users to its $149 Office Accounting Professional 2007 suite, but I suspect plenty of business owners will find that Express does everything they need.
